Bosch HDC400 1-1/8 In. Hex Chiseling Dust Collection Attachment;

The HDC400 dust collection attachment provides a unique dust collection system for breaker hammers. The ski-boot clamping band makes installation on the tool a snap. The clamp housing allows the attachment to be installed on the tool so that the dust collection shroud can be positioned near the chisel tip for optimum dust extraction. The clamp housing also can be adjusted up or down on the tool to accommodate a small variety of chisel lengths. The system also allows the dust collection shroud to float up or down should it make contact with the work piece during use. The dust port fits Bosch 1-3/8-inch vacuum nozzles but can also fit 1-1/4-inch/2-inch nozzles with the appropriate adapter.
